I created this simple program as a possible start to something larger while I continue to learn Python. It's a simple program that can be used to help young kids learn to count change in US currency.

I think this counts more as a puzzle than a game but I like it! I've developed a suite of Free Python Games for education at http://www.grantjenks.com/docs/freegames/ and I would be interested in including a simplified version. If you're interested in contributing, the code is on Github at https://github.com/grantjenks/free-python-games Created by Lance Spence on Mon, 22 Dec 2014 (MIT)
